I love Michigan!

Let me start by saying Aww Shit!
Come to find out there is a rather large rust hole hiding behind that fabulous diamond plate. But I'm not surprised, the floor was all but gone on that side to. This seems to be a big roadblock on the Aww Shit highway.
I cleaned out the hole as best as I could with a worn out wire wheel and then sealed it with undercoat until I can get it repaired.
